In this cohort of febrile infants, sedation with oral or intranasal midazolam reduced the risk of culture contamination during UC without causing serious adverse events. However, patients who were treated with sedation had longer length of stay in the ED.

Background Characteristics of obstructive sleep apnea (OSA) changes with age. Infants, toddlers and prepubertal children with OSA are usually underweight and may suffer from failure to thrive (FTT). Adenotonsillectomy (T&A) is the first line of treatment for OSA in childhood. In adults OSA is commonly associated with obesity and the metabolic syndrome. The change in body mass index (BMI) in adolescents with OSA following T&A was only sporadically studied. Thus, we peruse to examine the BMI z-score change following T&A in adolescents. Methods Clalit Health Services is the largest health care organization in Israel with the largest patient registry (more than 50% of the population). Two hundred and forty two adolescents aged 12–18 who underwent T&A between 2006 and 2015 were identified in the Clalit registry and their characteristics including height and weight were retrieved. The BMI z-score of these adolescents at baseline (up to 3 months prior to T&A) and during the consecutive 3 years after T&A were analyzed and compared. Results Changes in BMI Z-score were observed to all directions following T&A with overall small increase, not statistically significant (P = 0.26) from a median of 0.79 prior to T&A to a median of 0.835 after it. There was a minimal trend toward BMI z-score reduction in overweight children (n = 74) from 1.508 to 1.48 following T&A (p = NS), and in obese children (n = 33) from 2.288 to 2.000 (P = 0.06, 2 tailed). Interestingly thin individuals (n = 6) increased their BMI z-score following T&A from − 2.4 to − 0.59 (p = 0.046). Conclusions Adolescents show variable changes in their BMI z-score following T&A. In this aspect their BMI z-score change is closer to the change seen in adults treated for OSA and not that of young children. The changes observed show a trend toward normalization of the BMI z-score such that overweight children tend to decrease their BMI z-score while thin individuals tend to increase it.

Background: obstructive sleep apnea (OSA) is associated with different patient characteristics according to age groups. OSA in babies and in prepubertal children is usually accompanied by a failure to thrive (FTT) and underweight. Adenotonsillectomy (T&A) is the first line of treatment for obstructive sleep apnea (OSA) in childhood. In the adult population and partly in adolescents OSA is commonly associated with obesity and the metabolic syndrome. In adolescents with OSA managed with a T&A the change in BMI was only occasionally studied. Thus, we peruse to examine the BMI z-score change following T&A in adolescents. Methods: in Israel, Clalit Health Services is the largest health care organization with the largest patient registry (more than 50% of the population). From the Clalit registry, 242 adolescents aged 12-18 who underwent T&A between 2006-2015 were retrospectively studied. BMI z-score changes from up to 3 months prior to T&A were compared to BMI measures in the following 3 years post T&A.Results: there were changes to all directions with overall small increase, not statistically significant (P=0.26) in BMI Z-score with a median of 0.79 prior to and 0.835 following T&A. Overweight children (n=74) tended to reduce their BMI z-score from 1.508 to 1.48 following T&A (p=NS), and in obese children (n=33) BMI z-score decreased from 2.288 to 2.000 accordingly (P=0.06, 2 tailed). Interestingly thin individuals (n=6) increased their BMI z-score following T&A from -2.4 to -0.59 (p=0.046).Conclusions: adolescents managed with T&A show variable changes in their BMI z-score following the procedure. In this regard their BMI z-score change is closer to the change seen in adults treated for OSA and not young children. The changes observed show trend to normalize the BMI z-score such that overweight children tend to decrease their BMI z-score while thin individuals tend to increase it.
